Mr. Wise,

     I'm a slow (迟钝的) student. Most of my classmates are much better than me. So I usually get stressed

out. Although I spend much time studying for the tests, I can't get good grades, Sometimes my father gives

me some help. He tells me not to worry about it. But it doesn't work. What do you think I should do?
